What temperature would a conservatory need to reach for the structure to inrcur heat damage. (Talking plastic not wood or aluminium) What would be the nature of such damage if it occured ?

depend on plastic, but up around 50C for some plastics to start to
deform back to pre injected or pre extruded stresses*.

Not sure but ISTR Land River had some plastic fascias that simply became
unusable after been left in sunny car parks.
]
And a glass house in the sun CAN get well over 50C.

* I get tubs of things in vac formed plastic from the supermarket. I
keep em for freezing stuff in. They will deform with near boiling water.

But EP foam doesn't of course.

Shame it doesn't explicitly refer to "uPVC, conservatory windows for the
framing of", but this looks interesting:

Doesnt happen here, even tho we can have 10 days in a row over 100F.

Basically the plastic doesnt last as long as otherwise.
It doesnt melt or anything like that.

Byuckling and depending on the materiel catastrophic failure.

However unless you are going to turn it into a kiln, I'd suspect this would
not be an issue.
